Andrea the crocodile. Credit: Australia Zoo Crocodiles in northern Australia are altering their behaviour to try to keep cool as they experience increasingly stressful temperature extremes driven by climate change. New research has revealed that saltwater crocodiles (Crocodylus porosus) are spending more time at or close to their critical thermal limit of 32-33°C, diving less … Read more

This is a mobula ray. Many species of sharks and rays can jump out of the water. But, why do they do it? Image via Nico Marín/ Pexels. Leaping out of the water requires significant energy. This suggests breaching serves an important function. Sharks and rays leap out of the water for several reasons, such … Read more
Look closely. Can you spot the ring of light around the center of this galaxy, NGC 6505? ESA’s Euclid telescope captured galaxy NGC 6505, which is acting as a gravitational lens, bending the light from a more distant galaxy and creating this Einstein ring. See closeup below.
